Client-Side Encryption
Your data is encrypted directly in your browser using standard AES-256-GCM. The decryption key never reaches our servers.
VanishShare
Encrypted Self-Destructing File & Secret Sharing
Zero-Knowledge Ephemeral Secret Sharing
Share confidential credentials, passwords, and sensitive files without leaving a digital footprint.
Self-Destructing Timers
Set custom Time-to-Live (TTL) expiration limits. Secrets are permanently purged once expired or when download limits are reached.
Passphrase & OTP Verification
Protect sensitive payloads with an optional secondary passphrase and enforce multi-factor email verification for designated recipients.
Encrypted File Sharing
Safely transfer temporary certificates, private keys, and documents up to 200KB with complete end-to-end cryptographic protection.
How VanishShare Works
Three simple steps to exchange confidential data securely
1
Encrypt in Your Browser
A cryptographic 256-bit AES master key is generated locally using the Web Crypto API. Your secret note or file is encrypted before transmission.
2
Share the Zero-Knowledge Link
The decryption key is placed strictly in the URL hash fragment (#). Browsers never send hash fragments to web servers in HTTP requests.
3
Automatic Purge & Destruction
Upon decryption by authorized recipients or TTL expiration, the encrypted payload is permanently deleted from storage.
